SIMATIC S7-1200Siemens 6ES7222-1XF32-0XB0 SIMATIC S7-1200 SM 1222 8DO Relay Changeover PLC I/O Module
SIMATIC S7-1200 SM 1222 digital output module - 8 relay changeover DO, 2A each, 5-30VDC/5-250VAC.
Description
About the SM 1222, DQ 8x relay/2 A
About the SM 1222, DQ 8x relay/2 A
The Siemens 6ES7222-1XF32-0XB0 is a SIMATIC S7-1200 SM 1222 digital output module with 8 relay changeover-contact outputs rated 2 A each, switching 5-30 V DC or 5-250 V AC loads directly. It draws its logic supply from the S7-1200 backplane bus at 20.4-28.8 V DC, adding 140 mA of 5 V DC backplane load and 5 W of power loss.

Selection Notes
The changeover (SPDT) relay contacts switch AC or DC loads directly from the CPU without an external interposing relay, but short-circuit protection is not built in, so size external fusing or a circuit breaker to the 2 A rated current per channel. Relay life is rated at 10 million mechanical cycles but drops to 100000 at rated load current, so for high-cycle switching duty a solid-state output module is the better fit; choose this relay variant when the load is AC, mixed AC/DC, or exceeds the voltage range of transistor outputs.
Applications
Fits applications that need a PLC output stage to switch mains-referenced loads directly: contactor coils, indicator lamps, small solenoid valves, and mixed 24 V DC / 230 V AC control panels where isolating relay contacts avoid mixing supply domains on one output card.
